The q-jet is technically a variable cfm carburetor so you can't compare it directly to a holley or carter (this is why they were on big blocks and small blocks). The pre-1975 q-jets are 750cfm the post-1975 q-jets are 795 cfm.

i'm hoping that once i get done cleaning my Q and assemble it, it'll work....not sure if the rods need to be changed or what...... and size/etc..... all the internals look fine...but then again i'm not sure what i'm looking for either.......
u think there's a qjet rebuild kit available?.... or do i have to get a general rebuild kit?
